You need to determine which terminal will connect to your power source and which will lead to the load.
Step 4: Making Connections
Now, it’s time to make the connections:
For an SPST Switch:
- Connect the power source: Attach one end of a wire to the power source and the other end to one terminal of the switch.
- Connect to the load: Take another wire from the second terminal of the switch to your load (like an LED, motor, etc.).
For an SPDT Switch:
- Common terminal: Connect your power source to the common terminal.
- Leading to two outputs: Use one wire to connect to the “normally open” terminal and another to the “normally closed” terminal leading to different components or circuits.
Make sure to solder these connections for a durable joint. If soldering is new to you, practice on some spare wires.
Step 5: Insulating the Connections
After soldering, it’s crucial to insulate the connections to prevent short circuits:
– Heat Shrink Tubing: Slide heat shrink tubing over the connection before soldering. After soldering, use a heat source to shrink it around the connection.
– Electrical Tape: If you’re using tape, make sure to wrap it tightly over the soldered joint.
Step 6: Testing the Connections
Before finalizing your project, it’s imperative to test your connections:
– Set your multimeter to the continuity setting and place the probes on the switch terminals.
– Toggle the slide switch to ensure it effectively opens and closes the circuit.
If it fails to work, double-check your connections to ensure everything is securely soldered and insulated.
